AUTOMATIC HOPPER FEEDING DEVICE.

Application maximum- :1, 1925. semi I0. 3,7151.

Our invention relates to improvements in automatic hopper feedingdevices.

The object of our invention is to provide an automatic feeding devicefor rivets, bolts, nipples or any cylindrical member having heads orflanges, for feeding the same from a large hopper, one at a time intheir proper position, tea machine to be operated upon.

' Another object of our invention is to pro.-'

vide a feelercontrol which ermits of a very large reservoir for thestock of rivets, bolts, nipples or the like, and a small oscillatinghopper carrying a few rivets, bolts or the like, at a time, for causingthem to assume their proper position, thus re uiring little power tooperate and causing t e minimum abrasion by the tumbling action.

A further object of our invention is to provide means whereby rivets,bolts, nipples or the like, of different sizes, can be used by a slightadjustment of the slides in the chute and hopper, and which requires buta simple, single adjustment to accomplish the result.

A still further object of our invention is to provide a feeding deviceof this character which can be, readily connected up for delivery, toany machine, and thus roviding a simple and effective feeder, havlngcertain details of structure and combination of parts hereinafter morefully set forth.

In the accompanying drawings Figure 1 is a side view of our improvedautomatic hopper feeding device.

Figure 2 is an end view partly in section.

. Figure 3 is a top plan view.

Figure 4 is an enlarged transverse sectional view of the oscillatinghopper, on the line 4-4, Fig. -1.

Figure 5 is an enlarged transverse sectional View showing the adjustableslides for feeding rivets, boltsmr the like, of different sizes, takenon the line 55 of Fig. 1.

Referring now to the drawings, 1 represents the turret adapted to bemounted in the base 2, whereby it may be rotated in the base, so thatthe whole machine can be swung around so that the chute can be broughtinto proper position to feed the rivets, bolts or the like to themachine, all of which is well understood and needs no furtherdescription.

Mounted upon the turret 1, is a platform 3 adapted to support the motor4,'by means of which the shaft 5 is rotated through a gearing in thehousing 6, and a belt 8 passmg over pulleys 9 and 10, mounted on theshafts 11 and 12' of the motor and the gear ing. B this structure itwill be seen that the sha 5 is continuously rotated and which operatesthe feeding mechanism, and which feeding mechanism is automatically stoped by the rivets in the chute after a pre etermined number have enteredthe same.

Mounted on the platform 3, is a bracket supporting the large hopper 14arranged in an inclined position and having its lower end open andprovided with a plate 15, which is spaced from the open end of the hoper and carrying the stub shaft 16 upon w ich is rotatably mounted thefeeding wheel 17. The feeding wheel 17 is provided with the inwardlyextending members 18 inclined as shown, and with spokes 18 adapted topick up the rivets and carry them upwardly and discharge them into thechute 19, as will be hereinafter more fully described. The wheel 17, onits outer periphery, is provided with ratchet teeth 20 engaged by thepawl 21. The pawl 21 is pivotally mounted at 22, on

'the upper end of the L shaped lever .23.

This lever 23 is pivotally mounted at 24 to the platform 3, and has itslower end provided with a bearing surface 25 engaging the cam 26,rigidly mounted upon the shaft 5. By this structure it will be seen thatupon each rotation of the shaft 5, the lever 23 is rocked upon its pivot24, and the pawl 21 carried thereby, 1s reciprocated and it engages theteeth 20 of the feed wheel 17, the same is caused to rotate on'the stubshaft 16, and thus feeding the rivets, bolts or the like from the largehopper to chute 19, from which they are discharged to the oscillatinghopper, later described.

Pivoted upon the bracket 13, at 28, is the hopper 29, which receives therivets, bolts or the like from the chute 19 and this hopper 29 isprovided with a bracket 30, to which is pivoted the pitman 31, which hasits lower end pivotally connected at 32 to the crank 33, which isrigidly mounted upon the shaft 5, and which rotates therewith. By thisstructure it will be seen that the rotation of the shaft 5 oscillatesthe hopper 29 on its pivot 28, to cause the rivets to drop down into theslot 34, in the bottom of the hopper. The end of the hopper 28 isclosed, and is provided with an opening 35 to allow the heads of therivets, bolts or the like to'pass from the hopper, and above the opening35 are two pivoted guard fingers 36, which prevent therivets fromwedging in the opening, and also prevent the free passage of the rivetfrom the hopper when the body portion has passed through the slot 34.Rigidly carried by the brackets 13, adjacent the lower end of the hopper29, is a chute 37 which is composed of two plates 38 and 39, the outerplate 38 is adjustable toward the other plate by means of adjusting iton the studs 38 and 39, by means of nuts 40 and 41, so that the slot 40,between the two plates, can be varied for receiving rivets of differentsizes. The upper end of the slot 40 is in alinement with the slot 34 inthe hopper 29 so that upon each oscillation of the hopper, a rivet willpass from the slot 34 in the hopper 28, to the slot 40, in the slide.The hopper 29 has one half 42 adjustable so that the slot 34 may beadjusted for rivets, bolts or the like of different sizes, and this halfof the hopper is so mounted that the adjustment of the plate 38 of thechute carries with it the part 42 of the hopper 29. This chute, asshown, is in an inclined position, and thus the rivets, by gravity, willslide down and assume the position shown in Figure 1 of the drawings,with their heads abutting. In order to stop the rotation of the feedingwheel 17, when the desired number of rivets have entered the chute, weprovide the feeler 41, which is pivoted at 42, and has one end extendingover the slide 37 directly above the slot 40, so that the heads of therivets will hold the feeler upwardly, as will be later described. Whenthe feeler 41 is held raised by the heads of the rivets, after the slot40 is filled with rivets, the feeler is prevented from rocking upon itspivot 42. The pawl 21 carries a lateral shaft 22 which is mounted in theend of the L shaped lever 23 and adapted to oscillate therein. The saidshaft 22 of the pawl is provided with an arm 44', turned laterally atits outer end as indicated at 45, and extends over the outer downwardlyturned end 46 of the feeler arm 41. By this structure it will be seenthat every time the L shaped lever 23 is rocked by the cam 26, the pawlis moved forward, and the lateral extension 45 engages 46 of the feelerarm, and throws it lip so that the head of a rivet can pass the same inits downward movement in the slot in the slide. When the slot is filledup with rivets so that the feeler arm 41 is held upwardly, the end 46will be held downwardly away from the lateral projection 25, and thepawl 21 will remain out of engagement with the ratchet teeth 20, on thefeed wheel 17, and thus the feeding of the rivets from the hopper 14 tothe chute 19 will be stopped until all of the rivets in the oscillatinghopper'28 have passed into the slot 40 in the slide, and passed downbelow the lower end of the feeler arm. When this has taken place, thefeeler arm 41 drops, forcing the pawl 20 upwardly by the engagement ofthe end 46 with the lateral extension 45, and thus moves the pawl intoengagement and the ratchet teeth and the feeding mechanism again start.
